From my last feeding I learned that you have to use boiling water if you plan on doing the 5 gallon pail/paint mixer power drill combo. It's the only way to ensure all the sugar dissolves -the last batch from the previous update still had small crystals in them. You'll see in the pictures below that it crystallized in the feeding trays.
The hives were very active on the 8th, although it's hard to see from these pictures.
There was definitely some pollen sources around as you can see the pollen on the hind legs of the bee at the top of this photo.
The photo album below shows the feeders and the bees feeding.
I found this video in my normal reading and thought it might be interesting if you wondered where those boxes of bees come from. No commentary from Diana in this video.
